Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin
Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin
Retrospective Theses and Dissertations
In this paper, two methods for the design of active analog feedback bandpass filter pairs are examined. A third method is presented that does not use extra amplifiers for summation nor multicoupling. This third method uses identical bandpass amplifies and employs resistor summing to provide multicoupling. The name of this configuration is the "Dual Amplifier Bandpass Filter Employing Resistor Summing" (DABFERS). This configuration is economically attractive, has low sensitivity and better phase lag characteristics. In addition, third order prototypes are examined and a solution method for higher order prototypes is suggested.
